Letters Patent No. 59,838, dated November 20, 1866.

f. l SPECIFICATION. TO lALLWHOM IT MAY CONCERN:

Be it known that We, FREDERICK HENCKEL and WILHELM SECK, of Munich, Bavaria., have invented a new and improved machine for Peeling Grain, and we do hereby declare that the following is a full, clear, and exact description thereof, which Will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming a part of this specification, in WhichV Figure 1 represents a vertical central section of this invention, the plane of section being indicated by the line w, g. 2.

vFigure 2 is a horizontal section ofthe same taken in the plane indicated by the line y, y, Iig. 1.

:Figure 3 is a partial vertical section of the same, the line e, z, iig. 2, indicating the plane of section.

Figure 4 is a partial inside elevation of the peeling cylinder.

Similar letters of referenceindicate like parts.

The object of this invention is to remove the peel from grain by the centrifugal force imparted to the grain; said pecl, which consists of fibrous and silicious material, being of no value for nutriment. i

vThe apparatus which we use in carrying out our invention is composed of a cylindrical jacket, A, in which a drum rotates. This drum is formed'byone or more plates or stars, B, Whichare mounted on the vertical shaft, C. From the star, B, extend 6 ribs, D, to which the rings, E, and disks, F, are secured. From said ribs extend, in a radial direction, the fans, Gr, which, passing up through the entire height of the drum, produce a powerful draught.

To the inside df the rings E, a sieve, H, is secured, which serves to prevent the grain from dropping back into the centre of the drum.`

`The shaft C, isstepped in a suitable steel socket, J, and it has its bearing above inthe metalibox, K'. Motion is imparted to it by means f a belt stretched over a pulley mounted on the horizontal driving shaft L, which connects with the vertical shaft C, by means lof the bevel gear M. The horizontal shaft extends under the drum and it has its bearings-in suitable boxes in standards, N, which form the base ofthe whole apparatus.

The inner surface of the jacket A, is partially corrugated, as shown in fig. 2, and only those parts 0f the same are left smooth which are opposite the rings E, and disks F, as shown in lig. Y1. Between the periphery of the rings andthe inner surface of the surrounding jacket, an annular space of one sixteenth of an'inch (more or less) is'left, so that the drum revolves freely in the jacket. A portion of'the jacket is formed by the sieve, O, and in front of this sie'v'e a suitable box will be placed to receive the small fibres which separate freni the grain and are driven out of the sieve.

Inpractice there Will be 11 rings and 4 disks to each drum, and by these means I5l terraces ,or steps are formed, which communicate with each other through a series of holes, a, in the jacket, (see figs. 1 and 4,) in such a manner that both the first and second terraces from the top connect with the fifth, the third and fourth with thesixth, the fifth with the seventh, the sixth with the eighth, the seventh with the ninth, the eighth `with the tenth, the ninth and tenth vri/th the eleventh, the eleventh vith the twelfth, the twelfth with the thirteenth, the thirteenth with the fourteenth, and the fourteenth with the fifteenth, although it must he remarked that this connection can be changed and, in fact, must be changed with the number of terraces. In the .drawing only 9 terrdces are shown, and the connection is so arranged that the first terrace connects with the third, the third with the fth, the fifth with the seventh, and the seventh with the ninth, and in the same manner the second with the fourth, the fourth With the sixth, thesixth with the eighth, and the eighth with the ninth, or the connection may be made in any other suitable manner whereby the grain is compelled to pass over thc various terraces in a zigzag course. I

From the last terrace a spout, Q, serves to carry off the peeled grain. The communication between the several terraces, however, can be regulated by the slide R, an inside elevation of which is shown in Eg. 3. This slide is adjustable by means of a screw, S, and it serves to contract or `enlarge the channels of communi cation and to accelerate or retard the peeling processi The grain is introduced through a centrifugal feeder, T, which is composed of one or more disksmounted on the upper end of the shaft, C, and surrounded by a jacket, V, which is rinly secured to the top or cover of the jacket, A. By the action of the feeder, T, the grain is thrown against the jacket, V, and then it drops down through 4 channels, W, which lead down to the four top terraces. j

The operation is as follows: After the drum has attained a circumferential velocity of 2500 feet per minutc, the fans. produce a powerful current of air, which is sucked in at top and bottom and forced out through the sieve, O. The airl in -the jacket, A, therefore, is compressed. .The grain, afterpassing through the channels, W, to the terraces, is thrown by the centrifugal force against the inner surface of the jacket. By the combined action of the centrifugal force, of the pressure of the air, of the rolling motion on the corrugated Wall of the jacket, and of the friction of the grains or kernels against each other, the wood bl'e is gradually separated. On passing the sieve in each revolution the detached bres are blown out. The four ystreams of grain unite by the communication channels in two, and in this `state they'pass the succeeding terraces. In each terrace the same process takes place as on the rst four terraces. The peeled grains pass 0E through the spout, Q. l i Y,

It is obvious that this apparatus` can be made with more or less terraces than above specified, and the grain can be separated in a larger nr smaller number of currents, or it can be passed through the apparatus in a single current passing from one terrace to the other. j

The jacket can be made' of any suitable material, and the rings F may be supplied on their upper surfaces with oblique wings, which throw the grain against the inner wall of the jacket. y

We claim as new,l and desire to'secure by Letters Patent- 1. The method herein .described of separating the grain in two or more currents and uniting the saine again, consisting of the 'centrifugal feeder T, channels W, .terraces E, F, jacket A, and apertures a, substantially as described. Y

2. The adjustable slide, R, in combination with the apertures a, in the jacket-A, and with the several terraces of the revolving drum, when constructed and operating substantially as and for `the purpose described,
